    Standardizing includes to work from all directories?

    Most of the times I use relative links for my includes. So take for example the php file I have below:

    PHP Code:
    <?php
        
    include_once "includes/ezsql/ez_sql_core.php";
        include_once 
    "includes/ezsql/ez_sql_mysql.php";

        
    $db = new ezSQL_mysql('db','db','db','db.perfora.net:3306');
        
        
    /*$db->cache_dir = 'ezsql_cache';
        $db->use_disk_cache = true;
        $db->cache_queries = true;
        $db->cache_timeout = 24;*/
    ?>
    If I include this file fromt he root directory, everything is hunky dory. If I try to include it from any other directory, I obviously get crap, it can't find my files. So I was wondering, is there a way to standardize the paths so it works from any directory? I just don't want to create a different prep file for every sub-directory level. Sorry if this is a simple, no-duh question.

    I've tried using absolute paths, but then my server throws a fit and I get errors like this:
    Code:
    Warning: include_once() [function.include-once]: URL file-access is disabled in the server configuration in /homepages/23/d108630418/htdocs/bellevue/includes/prep2.php on line 2

    One option is to call it relative to the document root:
    PHP Code:
    include $_SERVER['DOCUMENT_ROOT'] . '/includes/file.php'
    Another option is to specify an include_path setting either in your PHP configuration, locally via .htaccess, or per script via set_include_path(); then just include the file name (or a path relative to the include path).

    If the includes are class definition files, you could also look into the __autoload() function (see http://www.php.net/manual/en/language.oop5.autoload.php).

    Start at the document root and add a leading slash to fully qualify the file path and still be domain independent. eg

    /docroot/path/to/file.php

    So this will do it dynamically.
    PHP Code:
    include getcwd ().'/file.php'
    (careful of the slash direction on Windows)

    (Whoooaaaa PHP tags button on quick reply, wahey, who said it would never happen)


    Edit:
    Doh sorry it will call from the current working directory which might not give you the correct path.

    Anti Linux rants are usually the result of a lack of Linux experience, while anti Windows rants are usually a result of a lot of Windows experience.

    Would something like this work?

    PHP Code:
        define('INCLUDES''includes/');
        
    define('TEMPLATE''template/');
        
    define('CONTENT''content/');
        
            
        require(
    getFilePath(INCLUDES.'ezsql/ez_sql_core.php'));
        require(
    getFilePath(INCLUDES.'ezsql/ez_sql_mysql.php'));
        require_once(
    getFilePath(INCLUDES.'config.php'));    
            
        function 
    getFilePath($relative_path) { 
            
    // $abs_path is the current absolute path (replace "\\" to "/" for windows platforms) 
            
    $abs_path=str_replace("\\""/"dirname($_SERVER['SCRIPT_FILENAME']));
            
    $relative_array=explode("/",$relative_path);
            
    $abs_array=explode("/",$abs_path);
            
    // for each "../" at the beginning of $relative_path
            // removes this 1st item from $relative_path and the last item from $abs_path
            
    while ($relative_array and ($relative_array[0]=="..")) {
                
    array_shift($relative_array);
                
    array_pop($abs_array);
            }
            
    // and implodes both arrays 
            
    return implode("/"$abs_array) . "/" implode("/"$relative_array);   
        } 
    Found it in the comments on the PHP.net site.

    Seems like a lot of extra work when you could just do:
    PHP Code:
    <?php
    set_include_path
    ($_SERVER['DOCUMENT_ROOT'] . '/includes/' PATH_SEPARATOR get_include_path());

    require 
    'ezsql/ez_sql_core.php';
    require 
    'ezsql/ez_sql_mysql.php';
    require_once 
    'config.php';
